python 编写进度条模块

def xxx():
    total = number
    for i in range(total):
	    if  i+1 == total:
		    percent = 100.0
		    print('当前核算进度 : %s [%d/%d]'%(str(percent)+'%',i+1,total),end='n')
	    else:
		    percent = round(1.0 * i / total * 100,2)
		    print('当前核算进度 : %s [%d/%d]'%(str(percent)+'%',i+1,total),end='r')
	    time.sleep(0.01)
